Abstract: Standard requirements for alk types of electrical control circuits for ac high-voltage
breakers rated above 1000 V are given. This standard is applicable for any type of power-operated
mechanism and for both ac and dc control power. Only basic control elements of the circuit break-
er, including reclosing where required, are included in this standard. Devices or circuits for protec-
tive relaying, special interlocking, etc., are not included.
Keywords: ac high-voltage circuit breakers, alarm circuits, auxiliary contacts, auxiliary switch,
closing, control schemes, electrical control, grounding, heater circuits, metal-clad switchgear,
metal-enclosed switchgear, motor circuits, opening, re-closing, tripping
